FIELD: electricity.SUBSTANCE: invention relates to electrical engineering and may be used in distribution devices with SF6 gas insulation. The switching mechanism for distribution device with SF6 gas insulation contains a fixed contact having an area of arcing contact and an area of the fixed main contact. A movable arcing contact and main contact can be moved in a straight-line motion. A cylindrical rod transfers driving force to the movable main contact and the movable arcing contact in order to start their straight-line motion. A joint bar is connected to the cylindrical rod. The fixed cylinder has a section of a hollow tube directing straight-line motion of the cylindrical rod and the joint bar. A spring accumulates elastic energy when the movable main contact and the movable arcing contact are moved to the contact position and it releases energy when the movable main contact and the movable arcing contact are moved to the separating position.EFFECT: sizes are decreased.4 cl, 4 dwg |
